However, in `merge-ort`'s case, we want to call the command e.g. in server-side software, where the actual error messages are not quite as interesting as machine-readable, immutable terms that describe the exact nature of any given conflict. With this patch, the `merge-ort` machinery records the exact type (as specified via an `enum` value) as well as the involved path(s) together with the conflict's message.
